Declare application SQL tables

The DB Sync client application code must declare the local tables used in the synchronization process. Fill a t_tabinfo array, and pass it to the dbsync_app.register_local_tables() function. If the app is on-line, it is also possible to query tables associated to the user with the dbsync_app.get_app_tables() function. However, this function cannot be used if the app is off-line and therefore it's better to hardcode the list of tables used by the app:

 DEFINE tabinfo dbsync_core.t_tabinfo
 LET tabinfo[1].table_name = "customer"
 LET tabinfo[2].table_name = "order"
 LET tabinfo[3].table_name = "cclines"
 LET s = dbsync_app.register_local_tables(tabinfo)
 IF s<0 THEN ... END IF
